Even if you do gain a minimal amount by removing the cat, it will come at a greater cost to the environment and human health. If your cat is clogged there is a thread on here on restoring it. It sounds like it is cheap.
The tiny bit of driving I do will contribute nearly zero to the pollution. Also unburned fuel, CO and NOx all readily break down in oxygen, and I live in Podunkistan. If I lived in a city with NOx smog issues my Outlook would be different, but frankly it isn't an issue in ND
